Title: Connector
Inventor: SUZAKI TOSHIHIRO
IPC: H01R12/16
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To strengthen fixing strength of a connector mounted on a printed wiring board and enhance workability in soldering. SOLUTION: A leg part 6 is extended backward from both right and left sides of an insulating material 2 of a connector 1, and a groove 6a is formed from the middle between upper and lower parts of the rear end surface of the leg part toward its front. A vertical width of the groove 6a is formed so as to make it almost equal to the thickness of a printed wiring board 9 to mount the connector 1. If the printed wiring board 9 is inserted in the groove 6a of the connector, after aligning the printed wiring board 9 and the connector 1, a terminal part 3a of a connector pin 3 is brought into contact with a circuit pattern on the backside of the printed wiring board 9, and the connector is temporarily fixed and reflow soldering can be applied. Since the connector 1 sandwiches the printed wiring board 9 between its upper and lower sides, resistive strength against a vertical torsion and a pressure from the front is enhanced.

Abstract: PURPOSE:To easily judge abnormality of the beam diameter by counting an effective output time of an output signal of a light beam detecting means, comparing its output time with a prescribed time of a reference and outputting an error signal, when said output time is outside of the range. CONSTITUTION:A laser beam 7 is brought to photoelectric conversion by a photodiode of the tip of an optical fiber 14, and brought to current - voltage conversion by an operational amplifier 16 and a feedback resistor 17. A voltage level of this output signal is compared with a reference voltage 19 by a comparator 18, and in case the output signal is higher than the reference voltage 19, a BD signal is outputted.

Title: Fuel injection device
Inventor: NAKAYAMA KENJI
IPC: F02D1/08
Filed: 1980-06-27
Abstract: PURPOSE: To improve the risetime and falltime fuel injection and bring the fuel injection characteristics closer to a square waveform, by a method wherein the injection period is determined through controlling the disphacement of a nozzle needle by controlling the pressure supplied to a needle holder, in a fuel injection device for Diesel engine.  
     CONSTITUTION: In the condition where compressed fuel is supplied from a fuel compressor 10 to an oil sump 21 at a fuel injection nozzle 17, when a control valve 37 is fully opened, the pressure in a chamber 29 of the needle holder 25 is rapidly lowered below the pressure applied from the oil sump 21, so that the nozzle needle 19 is moved upward and the fuel is jetted from a nozzle hoel 20. When the valve 37 is switched to a fully closed position, the pressure inside the chamber 29 is rapidly increased, causing the needle 19 to close the nozzle hole 20. Namely the opening and closing of the nozzle hole 20 is controlled by the change of pressure in the needle holder 25. Accordingly, the risetime and falltime of fuel injection can be improved, as compared to those in the case where a nozzle spring is used.

Filed: 1979-07-09
Abstract: PURPOSE:To contrive the improvement in the withstand voltage of the semiconductor device by projecting N-type collector layers at predetermined interval and forming N-type emitter layers through P-type base layers on the projected ends of the  collector layers to suppress the extension of a depletion layers from other portions at the base layers thereat. CONSTITUTION:P-type base layers 1a are projected vertically on the surface at predetermined interval as projections 11, and P-type base layers 2a are coated on the entire surfaces thereof. N-type emitter layers 3a are formed on the base layers 2a of the respective projections 11. When an operating voltage is applied, an depletion layer is extended perpendicularly with respect to the collector and base junction and the base layer 22 is extended in parallel with the main surface of the substrate 4a to deplete all the projections 11 so as to electrostatically shield the base 21 adjacent to the emitter layers 3a. Accordingly, the reduction of the effective base width is low due to the voltage rise between the collector and the emitter, the current amplification factor alpha is not increased unnecessarily, and even if the base layer is reduced in thickness, the withstand voltage between the collector and the emitter can be increased.
